c4f5326bb7 MDEV-6255 DUPLICATE KEY Errors on SELECT .. GROUP BY that uses temporary and filesort.
The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare
identically was seen as different strings.  (Space was handled correctly, but not NBSP)
This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by.

Fixed by removing all characters that compares as end space when creating a hash.

Other things:
- Fixed that --sorted_results also works for errors in mysqltest.
- Speed up hash by not comparing strings that has different hash.
- Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers.
  This was previously done for some functions, but not for all.
- Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.

785695e7c3 Flush DBUG log in case of DBUG_ASSERT()
Added strings_def.h into strings library to be able to have a DBUG_ASSERT() version without _db_flush() call (as strings.a should not depend on dbug.a)
Remove include of m_string.h in all string files (as it's included by string_def.h).
Fixed include order.
Changed "m_ctype.h" -> <m_ctype.h>
